Definitions

  • the wires were formed with a predetermined notch, by compression of a zone of the wire, to provide a predetermined break point.
  • the wires then were subject to alternate bending over a fixed bending angle until failure.
  • the results are plotted on the graphs of the drawings, on which the compositions of the wire are also shown.
  • the fine wires made of the alumina copper alloy, and containing the preferred range of about 4% copper, is particularly suitable to connect semiconductor crystal zones to terminals of a semiconductor frame by making a connection by means of ultrasonic welding.
  • the cross section of the dimension is not critical and, as required by the usual semiconductor manufacturing technology, can vary in the range of from about 0.01 to about 0.06 mm, preferably in a range of from 0.02 to 0.05 mm.
  • the wires are made in customary wire drawing technology, by drawing down wires to the desired size, starting with wires having an aluminum-copper alloy of between 3 to 5% copper--by weight, preferably about 4%.
